Like many, I have tried drugstore, expensive and ineffective. I then searched the internet advice care for my nails in poor states. I ordered Fungus stop without really believing it based on comments. I am amazed with the results. In a few days I saw a definite improvement by treating 3 times a day the first week, then 1 times a day as suggested. After four weeks, we can consider that my nails rid of these pesky fungi. Now we have to wait till I nail growth to regain a normal appearance, continuing the treatment for several months to avoid relapse. The vial contents permits treatment for many weeks by treating all toenails. I highly recommend it !!!
